BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention generally pertains to a laptop computer and moreparticularly to a camera latch that is incorporated into a laptopcomputer.

2. Description of the Related Art

Laptop computers generally consist of a lid for housing a display screensuch as an LCD and a base for housing various operational componentssuch as a processor, a hard drive, a disk drive, a modem, a battery,etc. The base also typically carries several input devices including akeyboard, a track pad (or track stick), and various buttons. In mostcases, the lid is hinged to the base so as to move the lid between aclosed position, placing the lid against the base, and an open position,exposing the display screen and the input devices to the user.

Most portable computers require that the lid be securely attached to thebase for transportation. As such, a locking mechanism is generallyprovided to secure the lid to the base when the lid is in the closedposition. The locking mechanism typically includes a hook, which extendsfrom the lid and which is configured for lockably engaging the base whenthe lid is in the closed position. The locking mechanism may alsoinclude a slide knob for slidably releasing the hook from the base so asto place the lid in the open position.

Various peripheral input output devices may be electrically connected tothe laptop computer. The peripheral I/O devices may include memory, diskdrives, keyboards, monitors, mice, printers, scanners, speakers anddigital cameras. In most cases, the peripheral I/O devices are connectedto laptop computer through wired connections using a serial, USB, orFirewire interface. In other cases, the peripheral I/O devices (as forexample keyboards and mice) are connected to the laptop through wirelessconnections such as radio or Bluetooth.

Digital cameras, in particular, have become increasingly popular inputdevices. The digital camera records images in digital form and feeds theimages to the laptop computer. The images may be downloaded into thelaptop computer as they are recorded or they may be stored in thedigital camera for downloading at a later time. Once in the computer,the images can be edited, copied, emailed, broadcasted, etc. Someexamples of digital cameras include webcams, point and click cameras andcamcorders. In all of these examples, the digital camera includes asensor that converts light into electrical charges. The image sensoremployed by most digital cameras is a charge coupled device (CCD),although complimentary metal oxide semiconductor (CMOS) may also beused.

Digital cameras and more particularly webcams, whose output is primarilyavailable for viewing over the Internet, may also be configured forvideo conferencing. Video conferencing generally refers to a liveconnection between two or more participants in separate locations forthe purpose of audio and video communication. At its simplest,videoconferencing provides transmission of images and text between twolocations. At its most sophisticated, it provides transmission of fullmotion video images and high quality audio between two or morelocations.

Although current laptop designs work well, in many instances it would bedesirable to provide laptops with improved and/or additionalfunctionality while maintaining aesthetics and keeping with the currenttrend of smaller and more powerful laptops.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention are discussed below with reference to FIGS.1-11. However, those skilled in the art will readily appreciate that thedetailed description given herein with respect to these figures is forexplanatory purposes as the invention extends beyond these limitedembodiments.

FIG. 1 is a perspective diagram of a portable computer 100, inaccordance with one embodiment of the invention. The portable computer100 generally includes a base 102 and a lid 104. The base 102 isconfigured to enclose various integrated circuit chips and othercircuitry that provide computing operations for the portable computer100. By way of example, the integrated circuit chips and other circuitrymay include a microprocessor, Read-Only Memory (ROM), Random-AccessMemory (RAM), a disk drive, a battery, and various input/output supportdevices. The base 102 is also arranged to hold a plurality of inputdevices such as a keyboard 106, a track pad 108 and button(s) 110.

The lid 104 is pivotally mounted to the base 102 via a hinge mechanism112. As such, the lid 104 may rotate to various positions between anopen position (FIG. 1A) and a closed position (FIG. 1B) relative to thebase 102. The lid 104 generally contains a liquid crystal display (LCD)114 that is used to display the graphical user interface (includingperhaps a pointer or cursor) as well as other information to the user.The LCD display 114 is generally surrounded at a peripheral region by abezel 116 that serves to support the LCD display 114 in its assembledposition within the lid 104.

The hinge mechanism 112 generally allows the lid 104 to pivot relativeto the base 102 so as to adjust the orientation of the lid 104 relativeto the base 102. For example, the lid 104 may rotate between an openposition and a closed position. In general, the open positioncorresponds to a lid orientation that allows a user to use the portablecomputer, i.e., the LCD display 114 and input devices 106-110 arevisible and accessible to a user, and the closed position corresponds toa lid orientation that allows a user to store or transport the portablecomputer, i.e., the base and lid are substantially flush with oneanother such that the LCD 114 and the input devices 106-110 are nolonger visible or accessible to a user.

In most cases, the hinge mechanism 112 is configured to hold the lid 104in its desired position (e.g., open, partially open or closed). Thehinge mechanism 112 may for example include a brake configured forexerting a frictional force on the lid 104 so as to maintain theposition of the lid 104 when the lid 104 is moved to the desiredposition. By way of example, a cam may be used to create the frictionalforce. In general, the cam moves between an engagement position,preventing the lid from slipping out of position, and a releaseposition, allowing the lid to freely rotate around the pivot. Otherbraking features may also be used as for example, friction washers,gears etc.

A locking mechanism 120 is also provided for securing the lid 104 to thebase 102 when the lid 104 is in the closed position. The lockingmechanism 120 generally includes a latch 122 that is received by a latchreceiving area 124 of the base 102 when the lid 104 is placed in theclosed position. The latch 122 and the latch receiving area 124 arecooperatively positioned so that when the lid 104 is closed, the twoelements engage with one another thus securing the lid 104 to the base102. As shown, the latch 122 protrudes from a top portion of the bezel116 (above the LCD 114) and the latch receiving area 124 is located inthe front portion of the base 102 (in front of the track pad 108).

The latch 122 and latch receiving area 124 can be widely varied. Forexample, the latch 122 may be fixed to the bezel 116 or it may bemovably coupled thereto so that it can be more easily positioned next tothe latch receiving area 124. The latch 122 may for example be pivotallycoupled to the bezel 116 so that it can rotate into engagement with thelatch receiving area 124. Furthermore, the latch receiving area 124 maycorrespond to the outer front surface of the base 102 or it maycorrespond to a cut out 126 in the base 102. The cut out 126 isgenerally configured to receive the latch 122 therein. The cut out 126may be used to place the back surface of the latch flush with the outerfront surface of the base 102 when the lid 104 is in the closedposition. By way of example, the cut out 126 may be a channel that runsthrough the entire front surface of the base 102 or it may be a recessthat only runs partially through the front surface of the base 102. Ineither case, the cutout 126 is set to receive the latch 122 when the lid104 is closed. The shape of the cut out 126 generally corresponds to theshape of the latch 122. This is typically done to eliminate voids orsubstantial breaks between the edges the latch 122 and cut out 126 whenthe latch 122 is mated within the cut out 126. The shapes may forexample include ovals, rectangles, squares, circles, etc or othercomplex shapes.

In one embodiment, the latch 122 and latch receiving area 124 includelocking features 128A an 128B that are cooperatively positioned so thatwhen the latch 122 is positioned next to the latch receiving area 124,the locking features 128 lockably engage with one another thus securingthe latch 122 to the base 102. The locking features 128 may be widelyvaried, and may for example include catches, plungers, hooks, flanges,slots, guides, and the like. In order to allow the lid 104 to be opened,the latch 122 or latch receiving area 126 may also include a latchrelease mechanism 130 for releasing the locking features 128 from theirlocking engagement. The latch release mechanism 130 generally includesan actuator for disengaging the locking features 128 and a biaser forproviding a spring action that pushes the latch 122 away from the latchreceiving area 124 when released. By way of example, the actuator maycorrespond to a knob, button, slider or switch that can be easilymanipulated by a user, and the biaser may be a spring, flexure ordeformable member

In another embodiment, the latch 122 is configured to carry a datacapture device 132 for capturing or collecting data. By integrating adata capture device into the latch, the space taken up by the laptop ispreserved, i.e., adding a data capture device does not compromise the x,y and z dimensions of the laptop. The data capture device 132 may beconfigured to capture audio data, image data, and/or the like. In thecase of audio data, the data capture device 132 may include a microphoneand in the case of image data the data capture device 132 may include acamera. The camera may be configured to produce a single image, imagesat intervals or a live video stream. In some cases, the data capturedevice 132 combines a camera and one or more microphones into a singleunit. In other cases, the data capture device 132 only includes one ofthese components. By way of example, the camera may include imagesensors such as charge coupled device (CCD) or complimentary oxidesemiconductor (CMOS) and optics such as lenses, splitters, filters andthe like. In addition, the microphone may include diaphragms,amplifiers, digital signal processors (DSP), etc.

To elaborate, the data capture device 132 may be mounted to the surfaceof the latch 122 or it may be embedded or enclosed inside the latch 122.When embedded or enclosed, the latch 122 typically includes an openingso as not to impede the line of sight of the data capture device 132.

In order to make the data capture device 132 more user friendly, thelatch 122 may be configured to move relative to the lid 104 rather thanbeing fixed thereto. By way of example, the latch 122 may pivot, swiveland/or translate relative to the lid 104 so that the position of thedata capture device 132 can be adjusted. The pivot action, (as shown byarrow 134), allows the latch 122 to rotate forwards and backwards, theswivel action (as shown by arrow 136) allows the latch 122 to rotateside to side, and the translating action (as shown by arrows 138 and140) allows the latch 122 to slide up and down or side to side,respectively. These types of motions may be particularly useful whenusing a data capture device such as a camera during video conferencing.The motions can be formed from various mechanism including but notlimited to one or more pin joints, slider joints, ball and socketjoints, flexure joints and the like. The motions can also be formed froma combination of joints as for example a pivot/translating joint,pivot/flexure joint, pivot/ball and socket joint, translating/flexurejoint, and the like. The motions can also be formed from various memorymaterials that can be bent, twisted or otherwise deformed in order toplace the latch 122 in the desired position.

As shown in FIG. 1C, the latch 122 may be detachable from the lid 104.This may allow a user to place the data capture device 132 in moreadvantageous position for capturing data. By way of example, this mayallow a user to use a latch camera as a point and click camera or alatch microphone as a speaker's or singer's microphone. If detachable,the lid 104 may include a docking station or latch bay 142 for receivingthe latch 122. The docking station 142 may be movable relative to thelid 104 or the removable latch 122 when attached may be movable relativeto the docking station 142 in order to provide the pivot, swivel and/ortranslation. A locking mechanism 144 may be provided between the latch122 and the docking station 142 in order to lock and release the latch122 to and from the lid 104. When detached, the data capture device 132contained within the latch 122 may be connected to the lid 104 throughwires or cables 146 that provide an electrical connection to theinternal components of the portable computer 100. Alternatively, thelatch 122 may include a memory module, battery and associatedelectronics thereby making the latch a fully operable stand alone deviceas for example a point and click camera. The latch may additionallyinclude a small LCD so that the user can view the images stored in thememory module. In cases such as these, the latch 122 may include aconnector that operatively couples with a connector located in thedocking station 142. In a similar vein, the latch 122 and dockingstation 142 may include wireless transceivers based on FM, RF,Bluetooth, 802.11, UWB (ultra wide band), IR, magnetic link (induction)and/or the like.

In another embodiment, the latch 122 is configured to carry one or moreindicators 148 for alerting a user to a particular status or a change instatus of the portable computer 100. By integrating an indicator intothe latch, the other surfaces of the laptop can be preserved, i.e.,adding an indicator does not compromise the surfaces of the base or lid.For example, latch 122 may include a power/sleep indicator that alerts auser as to when the computer 100 is on/off or in a sleep mode. Sleepindicators are typically illuminated when the computer is on, and notilluminated when the computer is off. Furthermore, sleep indicators mayturn on and off or cycle with increasing or decreasing intensity (ebb)when in sleep mode. The indicators 148 can be placed at any location onthe latch 122. Some positions may be more desirable than others. Forexample, the sleep indicator may be placed on the backside of the latch122 as shown so that it can be seen when the lid 104 is closed and thelatch 122 is engaged with the latch receiving area 124 of the base 102.

Although not shown, the indicators 148 generally include a light sourcesuch as an LED. The LED may be placed in an opening in the latch 122 orthey may be hidden within the latch 122. If the later, the latch housing123 may include a clear or translucent insert that is located in frontof the LED. The LED is configured to illuminate the insert. The insertmay include a light diffuser in order to hide the internal components ofthe latch while still allowing light to pass therethrough. Furthermore,the insert may be any shape. By way of example, the insert may be a logosuch as a computer manufacturer logo, or some other character or shape.In cases where there is limited space, the indicator 148 may includelight guiding or piping materials that allow the light source to beplaced at various locations within the latch 122. In some cases, theinsert may serve as both the indicator window and a light guidingmedium. Alternatively, the latch housing 123 may be formed from a clearor translucent material thereby eliminating the insert. The illuminablearea of the latch housing 123 may constitute a small portion of thelatch housing 123 or the entire latch housing 123 may be illuminable.Furthermore, a mask may be used to produce shapes like the insert whenutilizing a translucent latch housing.

It is contemplated that the portable computer 100 can be lap topcomputer such as an IBM compatible computer or an Apple compatiblecomputer. By way of example, the Apple compatible computer may includedifferent models such as the iBook, or Titanium models, which aremanufactured by Apple Computer, Inc. of Cupertino, Calif.

FIGS. 2A-2D are diagrams of laptop computer 150, in accordance with oneembodiment of the present invention. By way of example, the laptopcomputer 150 may generally correspond to the portable computer 100 shownand described in FIG. 1. FIG. 2A is a front elevation view of the laptopcomputer 150 in an open position. FIG. 2B is a side elevation view, incross section (taken substantially along line A-A) of the laptopcomputer 150 in the open position. FIG. 2C is a front elevation view ofthe laptop computer 150 in a closed position. FIG. 2D is a sideelevation view, in cross section (taken substantially along line B-B) ofthe laptop computer 150 in the closed position.

As shown, the laptop computer 150 includes a base 152 and a lid 154 thatis pivotable relative to the base 152 via a hinge mechanism 156. Thehinge mechanism 156 allows the lid 154 to pivot about axis 158 throughvarious angles a relative to the base 152. For example, the lid 154 maybe pivoted between the open position (as shown in FIGS. 2A and 2B) andthe closed position (as shown in FIGS. 2C and 2D). Although not shown,the hinge mechanism 156 may include a braking feature that holds the lid154 in its various positions between the open and closed position. Thebraking feature essentially allows a user to position the lid 154 at anyangle during use. In most cases, there is a maximum angle, whichcorresponds to the fully open position. The maximum angle is typicallysomewhere between about 90 degrees to about 180 degrees. The minimumangle is typically set at 0 degrees, i.e., at the interface between thelid 154 and base 152 when the lid 154 is in the closed position.

The lid 154 generally includes an LCD panel 160 that is surrounded atits periphery by a bezel 162. The lid 154 also includes a latch 164 thatis attached to the bezel 162. The latch 164 is configured to mate with acut out 166 in the base 152 in order to secure the lid 154 to the base152 and to produce an aesthetic looking enclosure when the lid 154 isplaced in the closed position. The latch 164 is generally dimensionedfor receipt within the cut out 166 so that it resides within the cut out166 when the lid 154 is closed. In most cases, the back surface 168 ofthe latch 164 is made flush with the outer surface 170 of the base 152in order to produce a substantially continuous outer surface when thelatch 164 is positioned within the cut out 166.

In order to lock the latch 164 to the base 152 and thus the lid 154 tothe base 152 when the lid 154 is in the closed position, the latch 164includes a latch-side locking feature 172 that is configured to lockablyengage a base-side locking feature 174. By way of example, the base-sidelocking feature 174 may be a plunger and the latch-side locking feature172 may be a hook that is capable of capturing the plunger. The positionof the locking features 172 and 174 may be widely varied, i.e., they maybe positioned at any of the mating surfaces between the latch 164 andthe cut out 166. In the illustrated embodiment, the latch side lockingfeature 172 is positioned on a front surface 176 of the latch 164, andthe base side locking feature 174 is positioned on a front surface 178of the base inside the cut out 166. In order to release the lockingfeatures 172 and 174 as for example the plunger from the hook, the latch164 also includes a slider 180. The slider 180 is slidably coupled tothe latch housing and is configured to disengage the locking features172 and 174 when translated from a first position to a second position.

The latch 164 is configured to carry a camera 184. The camera 184 mayfor example correspond to a digital camera such as a point and clickcamera, camcorder, web cam, videoconferencing camera or the like. Thecamera is disposed inside a latch housing 186, and is configured tocapture image data through an opening in the latch housing 186. By wayof example, the camera 184 may include a CMOS image sensor chip and alens assembly. The camera 184 may be attached to a portion of the latchhousing 186 and/or a printed circuit board located within the latchhousing 186. In fact, the PCB may be part of the camera 184. In mostcases, the camera 184 is electrically coupled to control electronics inthe base 152 through wires that extend from the PCB, through the bezel162 of the lid 154, through the hinge mechanism 156 and into the base152.

As shown, the latch 164 is pivotable relative to the bezel 162 via asecond hinge mechanism 188. The second hinge mechanism 188 allows thelatch 164 to pivot about axis 190 through various angles β relative tothe lid 154. For example, the latch 164 may be pivoted between a firstposition (as shown in FIGS. 2A and 2B) and a second position (as shownin FIGS. 2C and 2D). By providing a pivoting action, the position of thelatch 164 may be adjusted to place the latch 164 within the cut out 166when the lid 154 is closed or being closed and to place the latch 166 inmultiple camera viewing positions when the lid 154 is opened. Forexample, during a videoconference, the user can adjust the latchposition to place the line of sight 192 of the camera 184 on the user.

In most cases, there is a maximum and minimum angle β. The maximum angleβ is typically about 180 degrees so that the latch 164 lines up with therest of the lid 154 when the lid is opened. The minimum angle β istypically set at 90 degrees so that the latch 164 can be positionedwithin the cut out 166 adjacent the outer surface of the base 178 andnot closer than that to eliminate impinging the latch 164 when the lid154 is closed. It should be noted, however, that these maximums andminimums are not a limitation. For example, the maximum β may be closerto 360 degree in order to allow the latch 164 to pivot around the topsurface of the lid 154 so that the camera 184 can be used on the otherside of the lid 154. In cases such as this, the control electronics maybe configured to reverse the captured image(s) so that the image(s) isright side up when viewed as for example on the LCD 160.

Although not shown, the laptop computer 150 may include a positioningdevice for controlling the rotation of the latch 164 about the axis 190.The positioning device may be widely varied. For example, like the firsthinge mechanism, the second hinge mechanism may include a brakingfeature that holds the latch 164 in its various positions between thefirst and second position. The braking feature essentially allows a userto position the lid at any angle during use. The user simply grasps andpivots the latch 164 to the desired position. Once positioned, thebraking feature holds the latch 164 in the desired position. The brakingfeature may for example include friction washers, detents, gears and/orthe like.

Alternatively, an electronic actuator for rotating the latch 164 aboutthe axis 190 may be used. For example, the actuator may correspond to amotor such as a servo motor. The actuator may be housed in the latchhousing 186, the hinge mechanism 188, the bezel 162, the hinge mechanism156 and even within the base 152. The actuator may be directly coupledto the latch 164 or it may be indirectly coupled to the latch throughvarious motion transformers such as gears, cables, belts and the like.Furthermore, the actuator may be controlled directly through anelectronic switch or button dedicated to rotating the latch 164 orindirectly through software and the user interface of the laptopcomputer 150. For example, the user may press the arrow keys to move thelatch 164 to the desired position.

In one embodiment, the latch 164 is automatically positioned in a homeposition when the lid 154 is opened. The home position may be somepreset position set by the manufacturer or a position previously set bythe user. The home position may place the latch 164 in a position thatsets the appropriate camera viewing angle on the user or some otherangle as for example an angle that places the latch 164 in line with thelid 154. By way of example, the home position may be between about 0 and360 degrees, more particularly between about 90 and 270 degrees, andeven more particularly about 180 degrees. Even though a home positionmay be provided, it should be noted that in most cases the latch may bemoved from the home position to other positions once the lid is opened.This gives the user the ability to fine tune the position of the latch164 and thus the camera during use.

In addition, the latch 164 may also be automatically positioned in alock position when the lid 154 is closed. The lock position is typicallythe position that places the latch 164 within the cut out 166 adjacentthe outer surface 178 of the base 152 so that the locking features 172and 174 can engage with one another. That is, the lock position placesthe front side of the latch 164 next to the front surface 178 within thecut out 166. In some cases, the timing may set up so that as the lid 154finally closes, the latch 164 finally rotates into the cut out 166. Thatis, as the lid 154 is finally closing the latch 164 assumes the lockedposition.

In most cases, the positioning of the latch is configured to adjust orchange in accordance with the positioning of the lid. For example, asthe angle α increases in order to open the lid 154, the angle βincreases in order to place the latch 164 in the home position and asthe angle α decreases in order to close the lid 154, the angle decreasesβ in order to place the latch 164 in the locked position. In oneimplementation of this embodiment, the positioning device includes alatch tilting mechanism. The latch tilting mechanism is configured toconvert the rotation of the lid 154 about the axis 158 to rotation ofthe latch 164 about the axis 190. That is, when the lid 154 is opened orclosed, the latch tilting mechanism causes the latch 164 to pivot to thehome or locked positions. The latch tilting mechanism may include a beltthat rotatably couples an axle of the first hinge mechanism 156 to anaxle of the second hinge mechanism 188. In most cases, the belt travelsthrough the bezel 162 from the axle of the first hinge mechanism 156 toan axle of the second hinge mechanism 188. When the lid 154 is openedthus increasing α, the rotation of the axle causes the belt to move inthe clockwise direction. The clockwise motion of the belt in turn causesthe axle of the second hinge mechanism 188 to move in the clockwisedirection. Because the axle is mounted to the latch 164, the clockwisemotion of the axle causes the latch 164 to rotate about its axis in aclockwise manner thus increasing β. This clockwise motion cause thelatch 164 to pivot from the locked to home position. When the lid 154 isclosed, the reverse is true, i.e., everything moves in acounterclockwise motion. Although a belt is described in should be notedthat this is not a limitation and that the latch tilting mechanism mayinclude gears, cams, and the like.

The latch 164 is also configured to carry a symbol illumination system.The symbol illumination system operates to illuminate a symbol 196 on anilluminable portion of the latch housing 186 using light provided by alight source. The symbol 196 may be widely varied. For example, thesymbol 196 may be one or more characters, letters or numbers; a simpleshape such a circle, rectangle, square, triangle, etc., or it may be amore complex shape such as, icon, logo, etc. In one configuration, thesymbol 196 is an Apple corresponding to the Apple logo used by AppleComputer of Cupertino, Calif. The location of the symbol 196 can also bewidely varied. For example, it can be positioned on any surface of thelatch 164. In the illustrated embodiment, the symbol 196 is placed onthe backside 168 of the latch 164 so that it can be seen by the userwhen the latch 164 is positioned within the cut out 166.

The symbol illumination system may be widely varied. By way of example,the light source may be one or more light emitting diodes (LED), LCDpanels, light emitting semiconductor dies, lasers, incandescent lightbulbs, fluorescent light bulbs, neon tubes, and the like that producewhite or colored light. The light source may even correspond to the LCD160 contained within the lid 154. For example, the backlighting from theLCD panel may be used to illuminate the illuminable portion.Furthermore, the illuminable portion may be a clear or translucentportion of the latch housing 186 or it may be provided by a separatepiece of clear or translucent material that is inserted and affixedwithin an opening in the (translucent or non-translucent) housing. Byway of example, the illuminable portion may be formed from glass orplastic materials such as polycarbonate, acrylic and the like. Theilluminable portion may include a light diffusing means or colorfiltering means located either internal or external to the illuminableportion. As should be appreciated, the light diffusing means scattersthe transmitted light to produce a characteristic glow that emanatesfrom the outer surface of the illuminable portion, and the colorfiltering means allows certain colors to pass through thereby causingthe illumination portion to exude a certain color.

The light source is typically placed inside the latch housing 186 behindthe illuminable portion so that the illuminable portion can beilluminated thereby creating the symbol (e.g., lit up). Generallyspeaking, a symbol image is formed at the outer surface of theilluminable portion, and may even glow, when light is made incident onthe inner surface of illuminable portion via the light source. In caseswhere the light source cannot be placed behind the illuminable portion,a light directing element such as a light pipe or light guide can beused to direct the light from the light source to the illuminableportion. The light directing element may be a separate component or itmay be integral with the illuminable portion. The symbol illuminationsystem may additionally include a masking element for helping producethe desired symbol shape. The masking element generally includes anopening corresponding to the symbol image to be illuminated.

The light source of the symbol illumination system is typicallycontrolled by the control electronics stored in the base of the laptop150 so as to produce a symbol light effect having specificcharacteristics or attributes. For example, the light may be used toexhibit a behavior that reflects the desires or moods of the user, thatreflects inputs or outputs for the laptop computer 150, or that reactsto tasks or events associated with operation of the laptop computer 150.In most cases, illumination processing includes monitoring eventsassociated with the laptop computer 150 (e.g., software or hardware) andcontrolling the light source based on the monitored events so as toindicate a status corresponding to the monitored event. The events beingmonitored are generally identified by an operating system or amicroprocessor utilized within the laptop computer 150. The events cantake many forms such as operating system events or microprocessorevents. By way of example, the events may relate to signals, conditionsor status of the laptop computer 150 and/or to any devices or systemsattached thereto (e.g., i/o devices, internet, etc.). The light sourcemay be controlled in a manner that produces different symbol lighteffects for different events. For example, the light source may beconfigured to blink, ebb or produce different colors depending on theevents that occurred. The light source may produce a red blinking lightwhen a first event has been implemented, and solid blue light when asecond event has been implemented.

The illumination characteristics and their associated with specificevents may be stored in a database. Illumination characteristicsgenerally refer to how a light source is illuminated to produce a visualeffect (e.g., which lights are operated, how long the light sources areoperated, what color the light source output, etc.). The illuminationcharacteristics stored in the database may be accessed by a user througha light control menu, which may be viewed on the LCD as part of a GUIinterface. The light control menu may serve as a control panel forreviewing and/or customizing the illumination characteristics, i.e., theuser may quickly and conveniently review the illuminationcharacteristics and make changes thereto. Once the user saves thechanges, the modified illumination characteristics will be employed tohandle future illumination processing.

Referring to FIGS. 3-7 a latch assembly 200 will be described inaccordance with one embodiment of the present invention. The latchassembly 200 includes a latch 202 that is pivotally coupled to a bezel204. As shown, the latch 202 includes a latch housing 206 that ispositioned within a recess 208 in the bezel 204. The recess 208 andlatch housing 206 are dimension to allow the latch 206 to pivot withinthe recess 208. The latch housing 206 includes an axle 210 fixedthereto. The axle 210 may be a separate component or it may be integralwith the latch housing 206. When a separate piece, the axle 210 may beattached using any suitable attachment means, including press fitting,screws, bolts, adhesives, etc. In one example, the axle 210 is press fitinto a through hole in the latch housing 206.

As shown in FIG. 3, the axle 210 is received by a pair of bushings 212located on opposing sides of the latch housing 206. The opposing ends ofthe axle 210 extend through through-holes in the bezel 204 and aresupported by bushings 212 contained within the space provided between adisplay 214 and the bezel 204. The bushings 212 typically includethrough holes 216 for rotatably receiving the ends of the axle 210. Thebushings 212 may be separate components or they may be integrally formedwith the bezel 204. If separate, they may be attached using any suitableattachment means, including press fitting, snaps, screws, bolts,adhesives, etc. Because of this configuration, the latch 202 isconfigured to pivot relative to the bezel 204.

As shown in FIGS. 3, 4 and 7, the latch housing 206 is configured tocontain several components including a camera module 220, a lockingmechanism 222, and a symbol illumination system 224. The camera module220 includes at least a CMOS image sensor chip 226, a lens assembly 228and a printed circuit board 230. The CMOS image sensor chip 226 and lensassembly 228 are both mechanically and electrically coupled to the PCB230. The PCB 230 is structurally attached to an interior portion of thelatch housing 206 as for example using screws. The printed circuit board230 is electrically coupled to control electronics through flex wires232 that extend from the PCB 230, through an opening in the latch axle210, through the bezel 204. In laptop computers, the flex wires mayadditionally travel though a hinge mechanism and into the base. Theposition of the lens assembly 228 inside the latch housing preferableplaces the outer lens 234 of the lens assembly 228 adjacent an opening236 in the latch housing 206. The outer lens 234 may be recessed behind,flush with, or extend outside the latch housing 206 via the opening 236.In the illustrated embodiment, the outer lens 234 is substantially flushwith the outer surface of the latch housing 206 so that it sits withinthe opening, but not past it. This is generally done to both protect theouter lens and other components that it may interfere with it if itextended out of the latch housing 206.

The symbol illumination system 224 includes an insert 240 and one ormore LEDs 242. The one or more LEDs 242 are both mechanically andelectrically coupled to the printed circuit board 232 of the cameramodule 220. The insert 240 is positioned within an opening 244 in thelatch housing 206. By way of example, the insert 240 may be press fitinto the opening 244. The insert 240 is formed from a translucentmaterial. The translucency of the insert 240 is configured to allow thepassage of light therethrough while preventing the user from clearlyseeing or distinguishing objects through it as for example the LEDs 242or the printed circuit board 232. That is, the insert 240 transmitslight while causing sufficient diffusion to prevent perception ofdistinct objects located behind it. The insert 240 may, for example,include a light diffusing means located either internal or external tothe insert 240. In this embodiment, the LED(s) 242 are side firing LEDs,i.e., the light produced therefrom is made incident on the side surfaceof the insert 240. Any number of side-firing LEDs 242 may be placedaround the perimeter of the insert 240. The number of LEDs chosenpreferably produces enough illumination to emit a characteristic glowthat emanates equally from the outer surface of the insert 240. In oneconfiguration, the symbol illumination system 224 include red, blue,green and white LEDs that work together to produce the different colorsof the color spectrum (e.g., mixing). This particular arrangement allowsa laptop to change the color of the insert 240 according to specifictasks being performed in the laptop computer.

The locking mechanism 222 is not shown in great detail in FIGS. 3-7.These figures, however, do show a slit 250 in the latch housing 206. Theslit 250 is configured to receive a plunger 252 located on the base 254when the latch 202 is placed in the closed or locked position as shownin the previous figures. That is, when the lid is closed and the latch202 is positioned within a cut out 256 in the base 254, the plunger 252may be inserted into the slit 250 so that it can interact with a lockingfeature contained in the latch housing 206. These figures also show aslide switch 258 that is used by the locking mechanism 222 to disengagethe plunger 252 from the locking feature located behind the slit 250.The slide switch 258 is slidably coupled to the latch housing 206. Forexample, the slide switch 258 may include a rail that is retained withina channel in the latch housing 206. In most cases, the slider switch isflush with the outer surface of latch housing in order to preserve acontinuous look on the latch. Furthermore, the slider switch may includetactile bumps or knurls to help a user manipulate it.

Referring to FIGS. 8A-8D, the locking mechanism 222 will be described inaccordance with one embodiment of the present invention. As describedabove, the latch mechanism includes a slit 250 disposed in the latchhousing 206, and a slider switch 258 slidably coupled to the latchhousing 206. The slit 250 is cooperatively positioned with the plunger252 and is dimensioned to receive the plunger 252 therethrough when thelatch 202 is placed within the cutout 256 of the base 254. The plunger252 generally has a length that allows it to extend through the slit 250to engage a spring element 260 and hook 262 located within the latchhousing 206.

The spring element 260 is cooperatively positioned with the plunger 252,i.e., the central axis of the plunger 252 is substantially aligned withthe central axis of the spring element 260. The spring element 260 isconfigured to provide a spring resistance to the plunger 252 when theplunger 252 is inserted into the slit 250. That is, when the latch 202is pushed towards the base 254 using force F, the plunger 252 engagesthe spring element 260 and the force F works against the spring force ofthe spring element 260 until the latch 202 is placed in its desiredposition relative to the base 254. The spring element 260 can be widelyvaried. For example, it may correspond to a flexure, a cushion ordeformable member, a spring, and the like. In the illustratedembodiment, the spring element 260 is a tension spring that is retainedon a post 264 that protrudes out of the interior surface of the latchhousing 206. When the latch 202 is closed, the spring element 260 in theform of a tension spring is compressed between the plunger 252 and thelatch housing 206.

The hook 262 is positioned in the same plane as the plunger 252 and isarranged for lockably receiving the plunger 252 when the plunger 252 isinserted into the slit 250. The hook 262 is configured to rotate betweena plunger receiving position for capturing the plunger 252 (as shown inFIG. 8A), and a plunger releasing position for releasing the plunger 252(as shown in FIG. 8D). This is generally accomplished via a pivot pinthat passes through the hook 262 and which is seated in the latchhousing 206. As should be appreciated, when the hook 262 is placed inthe latch receiving position, the hook 262 captures the plunger 252thereby securing the latch 202 to the base 254. Conversely, when thehook 262 is placed in the latch releasing position, the plunger 252 isreleased from the hook 262, and the latch 202 is left unsecured relativeto the base 254. Once unsecured, the both the lid and latch can betilted as described above. Although not a requirement, the entire hook262 is located inside the latch housing 206 at all times (e.g. bothpositions) to eliminate unsightly and harmful protrusions emanating fromthe latch 202.

A spring element 268 is used to continuously exert a biasing force onthe hook 262 so as to place the hook 262 in the plunger receivingposition. The spring element 268 causes the hook 262 to rotate about thepivot axis until it reaches a stop surface 270 that determines the latchreceiving position. The stop surface may be widely varied. For example,it may be a portion of the latch housing 206 or the slider switch 258.In the illustrated embodiment, the stop surface 270 is formed by aflange 272 of the slider switch 258. In this manner, the spring element268 also exerts a biasing force on the slider switch 258 thereby placingthe slider switch 258 in its first position against an abutment stoplocated on the latch housing 206.

Because of space limitations, the spring element 268 generallycorresponds to a torsion spring. The torsion spring has one endconnected to the latch housing 206 and another end connected to the hook262. As such, the torsion spring exerts a force on the hook 262 relativeto the latch housing 206. It should be noted that the spring element 268is not limited to torsion springs that other types of spring elementsmay be used. By way of example, compression and tension type springs maybe used. Furthermore, deformable members or flexures may also be used.In fact, in some cases, the hook may be a flexure.

The slider switch 258 is configured to free the hook 262 from theplunger 252. The slider switch 258 allows a user to move the hook 262from the plunger receiving position to the plunger releasing positionusing a simple translating motion. This is generally accomplished withthe flange 272 that extends out of the slider switch 258 and thatengages one end of the hook 262 thereby causing the hook 262 to rotateabout its axis when the slider switch 258 translates from a firstposition to a second position. The slider switch 258 is generally biasedin the first position via a spring force. The spring force may beprovided by a third spring element or the second spring element 268associated with the hook 262.

The operation of the locking mechanism 222 will now be described. Inorder to lock the latch 202 to the base 254, the latch 202 is pushedagainst the base 254 by a force F provided by a users hand or finger. Asthe latch 202 nears the base 254, the plunger 252 travels through theslit 250 and engages the spring element 260 contained within the latchhousing 206. Because the spring element 260 is a tension spring, thetapered tip 274 of the plunger 252 nestles into the opening in thetension spring upon engagement. Once engaged, the force F works againstthe spring force in order to further advance the plunger 252. When theplunger 252 reaches the hook 262, the tapered tip 274 of the plunger 252pushes against the tapered surface 276 of the hook 262 (cam action)thereby causing the hook 262 to rotate about its axis against the springforce provided by the second spring element 268. When the tapered tip274 of the plunger 252 passes the tapered surface 276 of the hook 262,the hook 262 collapses back towards the plunger 252 via the spring forceprovided by the second spring element 268 thereby capturing the tip 274of the plunger 252 within the catch of the hook 276. At this point thelatch 202 is locked to the base 254.

In order to unlock the latch 202 from the base 254, the slider switch258 is translated relative to the latch housing 206 by a force F₂provided by a users finger or hand. As the slider switch 258 translatesfrom the first position to the second position, the flange 272 of theslider switch 258 pushes against the hook 262 thereby causing the hook262 to rotate about its axis against the spring force provided by thesecond spring element 268. When the hook 262 reaches the plungerreleasing position, the plunger 252 is no longer captured by the hook262 and the first spring element 260 provides a spring force against theplunger 251 that pushes the latch 202 away from the base 254. As thelatch 202 moves away form the base 254, the plunger 252 exits the slit250 thereby releasing the latch 202 from the base 254.

FIGS. 9A and 9B are simplified side views of a laptop computer 300, inaccordance with one embodiment of the present invention. The laptopcomputer 300 includes a base 302 and a lid 304 that is pivotable coupledto the base 302 via a lid axle 306. The lid axle 306, which is attachedto the lid 304 may for example be supported by bushings that areattached to the base 302. The lid 304 is positionable between an openposition (as shown in FIG. 9B) and closed position (as shown in FIG.9A). The closed position is generally set by the interface between thebase 302 and the lid 304, i.e., the position that places the lid 304adjacent the base 302 as shown in FIG. 9A. The open position isgenerally some angle α that allows a user to view a LCD panel 308disposed inside the lid 304. The angle α may be widely varied. In theillustrated embodiment, the closed position corresponds to a positionthat places the lid 304 substantially 0 degrees relative to the base 302as shown in FIG. 9A, and the open position corresponds to a positionthat places the lid 304 substantially 90 degrees relative to the base302 as shown in FIG. 9B. Although there is a designated open position,it should be noted that the open position may be adjusted to otherpositions during use. For example, some users may prefer to place thelid 304 at an angle greater than 90 degrees for better viewing,especially when the laptop computer 300 sits low compared to the user.

The lid 304 includes a camera latch 310 that is pivotally coupled to thelid 304 via latch axle 312. The latch axle 312, which is attached to thelatch 310 may for example be supported by bushings that are attached tothe lid 304. The latch 310 is positionable between a home position (asshown in FIG. 9B) and locked position (as shown in FIG. 9A). The lockedposition is generally set by the interface between the camera latch 310and the base 302, i.e., the position that places the camera latch 310adjacent the base 302 as shown in FIG. 9A. The home position isgenerally some angle β that places the line of sight of a camera 314 ofthe camera latch 310 on the user. The angle β may be widely varied. Inthe illustrated embodiment, the locked position corresponds to aposition that places the camera latch 310 substantially 90 degreesrelative to the lid 304 as shown in FIG. 9A, and the home positioncorresponds to a position that places the camera latch 310 substantially180 degrees relative to the lid 304 as shown in FIG. 9B. Although thereis a designated home position, it should be noted that the position ofthe camera latch 310 may be adjusted from the home position to otherpositions during use. For example, tall users may prefer to place thecamera latch 310 at an angle greater than 180 degrees while short usersmay prefer to place the camera latch 310 at an angle less than 180degrees.

The laptop computer 300 also includes a latch tilting mechanism 316. Thelatch tilting mechanism 316 is configured to automatically place thecamera latch 310 in the locked position when the lid 304 is placed inthe closed position, and to automatically place the camera latch 310 inthe home position when the lid 304 is placed in the open position. Thelatch tilting mechanism 316 includes a latch belt 318. The latch belt318 is operatively coupled to the both the lid axle 306 and the latchaxle 312. The latch belt 318 extends through the lid 304 between the lidhousing 320 and the flat panel 308 contained therein. Rollers 322 may beprovided to maintain the belt position between the lid housing 320 andthe flat panel display 308. Alternatively, the belt 318 may rub againstthe surface of the flat panel 308 instead of using rollers 322.

As shown, the belt 318 is draped around the latch axle 312 and one endof the belt 318 is attached to the lid axle 306 and the other end of thebelt 318 is attached to a tension spring 324 that is fixed to the lidhousing 320. The tension spring 324 keeps the belt 318 under constanttension. The tension spring picks up any slack in the belt 318 therebyensuring contact between the belt 318 and the latch axle 312.Alternatively, the tension spring may be replaced by a belt capable ofstretching, i.e., the tension force is provided by the flexing of thebelt. When the lid axle 306 is rotated from the closed to open position,the belt 318 is unrolled from the lid axle 306 and when the lid axle 306is rotated from the open to closed position, the belt 318 is rolled uponto the lid axle 306. During both unrolling and rolling, the belt 318moves over the latch axle 312 thereby causing the latch axle 312 torotate about its axis. During unrolling, the latch axle 312 rotates in afirst direction thereby causing the camera latch 310 to tilt to the homeposition. During rolling, the latch axle 312 rotates in a seconddirection thereby causing the camera latch 310 to tilt to the lockedposition.

The diameters of the axles 306 and 312 may be adjusted to effect therotation of the latch 310 relative to the rotation of the lid 304. Ifthe latch axle 312 and the lid axle 306 have the same diameter, thelatch axle 312 will have the same amount of rotation as the lid axle306. By way of example, if the lid 304 is rotated 90 degrees relative tothe base 302 then the latch 310 will be rotated 90 degrees relative tothe lid 304. Alternatively, if the latch axle 312 has a greater diameterthan the lid axle 306, the latch axle 312 will have less rotation as thelid axle 306. By way of example, if the lid 304 is rotated 90 degreesrelative to the base 302 then the latch 310 will be rotated less than 90degrees relative to the lid 304. In addition, if the latch axle 312 hasa smaller diameter than the lid axle 306, then latch axle 312 will havemore rotation than the lid axle. By way of example, if the lid 304 isrotated 90 degrees relative to the base 302 then the latch 310 will berotated more than 90 degrees relative to the lid 302.

Referring to FIGS. 10A and 10B, the latch tilting mechanism 316 will bedescribed in greater detail. FIG. 10A is a diagram of the camera latchportion of the camera tilt mechanism 316. FIG. 10B is a diagram of thelid portion of the camera tilt mechanism 316. As shown, a first end ofthe belt 318 is attached to the flat tension spring 324 that in turn isattached to the back of the lid housing 320, and a second end of thebelt 318 is attached to the lid axle 306. Furthermore, both the latchaxle 312 and the belt 318 (in the region of the latch axle 312) haveteeth 330 separated by notches 332. The teeth 330 are configured toengage one another thereby causing the latch axle 312 to rotate aboutits axis when the belt 318 is rolled or unrolled relative to the lidaxle 306. In essence, the teeth 330 of the belt 318 mate with the teeth330 on the latch axle 312 in order to drive the positioning of the latchaxle 312. When the lid axle rotates, the teeth located on the beltengage the corresponding teeth located on the latch axle. As the lidaxle further rotates, each tooth engages another tooth thereby causingthe latch axle and thus the latch to rotate about its axis.

Because of the tension spring 324, the camera latch 310 can be tiltedaway from the home position set by the mated teeth by asserting enoughforce to advance the latch axle 312 to the next notch position. This isaccomplished without causing any rolling or unrolling of the belt 318,i.e., the position of the belt 318 stays stationary. The user simplypushes or pulls on the latch 310. When the pulling or pushing force isgreat enough, the latch axle 312 is caused it to slip relative to thebelt 318 thereby causing the next tooth on the latch axle 312 to engagethe next notch on the belt 318, i.e., the pulling or pushing forceovercomes the tension force and any forces found between the matedteeth. In most cases, the slipping teeth create a click that gives theuser the ability to feel when the camera latch 310 has moved to the nextposition. That is, the teeth serve as detents that provide a tactile wayfor the user to know when the latch camera 310 has reached a certainposition. The number of latch positions generally corresponds to thenumber and dimensions of the teeth and notches. It is generally believedthat more closely packed teeth/notches produces greater resolution. Thatis, the more closely packed teeth/notches, the smaller the incrementalchanges in distance moved by the latch axle and thus the camera latch.As should be appreciated, if there are N equidistance teeth/notchpositions, discrete tilt angles of 360/N are possible.

FIG. 11 is a block diagram of a computer system 350, in accordance withone embodiment of the present invention. The computer system 350 may forexample correspond to a laptop computer such as any of those previouslydescribed. As shown, the computer system 350 includes a processor 356configured to execute instructions and to carry out operationsassociated with the computer system 350. For example, using instructionsretrieved for example from memory, the processor 356 may control thereception and manipulation of input and output data between componentsof the computing system 350. The processor 356 can be a single-chipprocessor or can be implemented with multiple components.

In most cases, the processor 356 together with an operating systemoperates to execute computer code and produce and use data. The computercode and data may reside within a program storage block 358 that isoperatively coupled to the processor 356. Program storage block 358generally provides a place to hold data that is being used by thecomputer system 350. By way of example, the program storage block mayinclude Read-Only Memory (ROM) 360, Random-Access Memory (RAM) 362, harddisk drive 364 and/or the like. The computer code and data could alsoreside on a removable storage medium 366 and loaded or installed ontothe computer system 350 when needed. Removable storage mediums include,for example, CD-ROM, DVD, PC-CARD, floppy disk, magnetic tape, and anetwork component.

The computer system 350 also includes a display device 368 that isoperatively coupled to the processor 356. The display device 368 isconfigured to display a graphical user interface (GUI) including perhapsa pointer or cursor as well as other information to the user. By way ofexample, the display device 368 may be a monochrome display, colorgraphics adapter (CGA) display, enhanced graphics adapter (EGA) display,variable-graphics-array (VGA) display, super VGA display, liquid crystaldisplay (e.g., active matrix, passive matrix and the like), cathode raytube (CRT), plasma displays and the like.

The computer system 350 also includes input/output (I/O) circuitry 370that is operatively coupled to the processor 356. The I/O circuitry 370includes one or more controllers that may be integrated with theprocessor 356 or that may be separate components. The I/O circuitry 370is generally configured to control interactions with one or more I/Odevices 372 that can be coupled to the computer system 350. By way ofexample, the I/O devices 372 may be internal or peripheral devices suchas memory, disk drives, keyboards, mice, track pads, printers, scanners,speakers, video cameras, music players and the like. The I/O devices 372may also be network-related devices such as network cards or modems. Asshould be appreciated, each of these devices may include a separatemicrocontroller for processing data at the device.

The I/O circuitry 370 generally operates by exchanging data between thecomputer system 350 and the I/O devices 372 that desire to communicatewith the computer system 350. In some cases, the I/O devices 372 may beconnected to the I/O circuitry 370 through wired connections. When theI/O devices 372 are integrated into a single unit as for example a baseof a laptop computer, the devices 372 are typically hard wired (unlessthey can be removably detached). When the I/O devices 372 are standalone devices, the I/O devices 372 are typically connected throughcables and connectors such as USB or Firewire. The I/O circuitry 370 mayadditionally include one or more media bays (expansion bays) capable ofreceiving media bay devices (expansion bay devices) to provide greaterresources to the computer system. The media bays are accessible fromexternal to the computer system so that media bay devices can be easilybe inserted into the media bays or removed from the media bays. Theremovability of the media bay devices allows a few media bays to supporta variety of different types of devices in a flexible manner.Alternatively, the I/O devices may be connected to the I/O circuitry 370through wireless connections. By way of example, the data link maycorrespond to PS/2, USB, IR, RF, Bluetooth or the like.

In the illustrated embodiment, the I/O devices 372 include at least akeyboard 374, a tracking device 376, a disk drive 378, a camera module380 and a symbol illuminator 382. The keyboard 374 is configured todeliver input commands and other instructions to the computer system350. The tracking device 376 is configured to deliver movement commands,i.e., the tracking device may be used to move a cursor or pointer or toimplement a scrolling function on the display screen. The trackingdevice 376 may take the form of a mouse, a track ball, a touch pad, astylus, a tablet and the like. The disk drive 378, which facilitatestransporting such data to other computer systems, is configured to storevarious types of data. The camera module 380 is configured to record andstore images in digital form, and to feed these images to the processor356. Furthermore, the symbol illuminator 382 is configured to producelight in a controlled manner via one or more light sources. The lightsources may for example be operatively coupled to the processor 356. Thelight may be used to indicate a status of the computer system 350.

While this invention has been described in terms of several preferredembodiments, there are alterations, permutations, and equivalents, whichfall within the scope of this invention. For example, although theinvention is primarily directed at a camera latch for a laptop computer,it should be noted that concepts disclosed herein may also be applied toother electronic devices, including but not limited to PDAs, musicplayers, mobile phones and the like or I/O devices such as monitors,televisions and the like. It should also be noted that there are manyalternative ways of implementing the methods and apparatuses of thepresent invention. For example, although the locking mechanism wasdescribed as including both a hidden locking feature (hook) and anexposed locking feature (plunger), it should be noted that in some casesthe plunger may be hidden. As should be appreciated, plungers may beunsightly and potentially dangerous. A protruding plunger may result inthe plunger being accidentally sheared off when it comes into contactwith some other object. Also, if the plunger is accidentally slammed ona finger, or if the plunger hooks on clothing, it can cause injury ordamage, leaving a negative impression on the user. By way of example,the hidden plunger may be extracted from the base using magnetic lockingsystem as described in U.S. Pat. No. 6,659,516. Furthermore, in somecases, it may be desirable to reverse the automatic positioning of thelatch relative to the base once the latch is placed in the home positionand the lid is opened in order to ensure that the line of sight of thecamera is directed at the user. For example, as the angle α increases,the angle β decreases and as the angle α decreases, the angle increasesβ increases in order to keep the line of sight directed at the user.
